- A heliostat throws sunlight where it might be needed, whether for photography or scientific observations. This example resembles the Foucault heliostat made by the Société Genevoise. A tag on the base reads: “PRESENTED TO COLUMBIA UNIVERSITY BY ERNEST KEMPTON ADAMS.” Ernest Kempton Adams was a graduate of Columbia University. Following his untimely death in 1904, his large collection of scientific and engineering instruments was given to Columbia, and his father provided $50,000 to support physical research.
